Many readers will be familiar with the name Bit Torrent, yet might be less familiar with the creator of Bit Torrent, Bram Cohen.

We've been lucky enough to grab a few minutes of Bram's time and talk to him on a variety of issues; Bram talks about his views on piracy, the growth in Bit Torrent use, and the protocol's use for software piracy.

Click "read more" to see what Bram has to say.

View: How does Bit Torrent Work?


Firstly, could you tell us about yourself, your history?

I've been into recreational mathematics most of my life, and worked in software startups for a while after dropping out of college before starting work on BitTorrent.

Tell us about BitTorrent- what was the inspiration? What were you trying to achieve with the protocol?

I had a lot of experience working on networking protocols, and was interested in exploring what I thought were the reasonable problems to work on. My main goal was to make it cheap to distribute large, popular files, which I of course succeeded in doing.

BitTorrent, it was recently suggested, was carrying as much as 30% of the webs traffic; how did you re-act to this news?!

I don't have any visceral concept of how much that bandwidth that really is, so it's mostly just surreal.

Moving onto BitTorrent uses at the moment - it'd be hard to ignore the arguably most common use of the protocol - piracy. How do you feel about this? Did you think about the potential for 'abuse' when you conceived the protocol?

Given the history of such tools, it's fairly obvious that the general public has a strong interest in piracy.

A group have created a new program called eXeem which appears to solve one of the problems BitTorrent has- that off tracking torrents. Have you seen the program, and if so, what do you think of it?

It's yet another napster/kazaa/edonkey/hotline/whatever. BitTorrent usage is doing quite well without it.

Moving on, the protocol has clearly many legitimate uses; have you seen any especially unique implementations?

They're all just pushing around bits, which is about all I care about.

How do you think companies are going to deal with bandwidth in years to come - do you think it will be something along the lines of bit torrent, or something radically different?

Peer to peer as an approach is here to stay.

What's cool technology wise in the Cohen house hold at the moment? What'd be your pick for the "next big thing"?

I've also been working on the Codeville version control system and designing twisty puzzles. I don't know what the next big thing is.

Finally, what does the future hold for yourself?! What are you working on at the moment?

I'm continuing to work on BitTorrent.

Good job for Neowin with all these interviews lately, I like it

Except when the questions are longer than the answers.

Should have asked him about what he thinks of exeem and its *******ization of bittorent
#2.1 illz55 on 08 Feb 2005 - 21:18
Are you blind or just lazy, maybe both? He did answer a question about exeem.

Good questions, poor answers.

It would be nice to see more than just one sentence as an answer, he didn't seem to even try and answer the questions. At least that is how it reads to me.
#3.1 illz55 on 08 Feb 2005 - 21:19
Yeah, but then again "unprofessional journalism" is what Neowin does and that is what you'll get.
#3.2 Thrawn on 08 Feb 2005 - 21:56
Agreed. And I doubt he's busy enough to justify this poor interview. I think that perhaps he's only adept at communication in binary, computer geek you know
#3.3 Jugalator on 08 Feb 2005 - 22:37
I saw it more as he tried to answer the questions, but didn't want to / couldn't answer some of them.

It's understandable if he doesn't want to comment much on piracy, try to get into a fight with exeem by spewing arguments against it, and also hard to foresee the future so questions related to that went unanswered as well. He just seems like a guy who carefully thinks his answers over to me.

Not a coincidence he gave a more thorough answer about inspiration for BT, etc. It's stuff he can easier answer without getting controversial or anything.
#3.4 carl0ski1 on 09 Feb 2005 - 12:54
not brians fault the questions were bad

the questioned were very closed and short answers.

They needed more open ended questioned that he'd need to give a more detailed answer.

Yes
It's ok
= bad questioned

but some were good but i guess he was short nd sweet in those to cover his own ass

If he even hints that he suspected that his technology was ideal at piracy while developing it he's in deep sh!t

Why would you think that? Even if BitTorrent is a popular tool for piracy, it clearly has legitimate uses. Even if it didn't, there are no laws against developing software purely for piracy. If you host a central server through which pirated files pass, you'll get shut down, but that's because they can push on the issue of pirated files, they have no ground to stand on regarding the issue of developing software to facilitate piracy - it doesn't become illegal until it's used for that purpose, and at that point, it's not the responisibility of the author what you do with it.
#3.6 spUrr on 10 Feb 2005 - 05:12
exactly, I can think of other protocols such as http, nntp and apps like IE that are more than capable of sustaining piracy
(2 replies) #4 take_the_veil on 08 Feb 2005 - 21:19
Well, like he said, BT was and will do quite well without exeem.
#4.1 ThaCrip on 09 Feb 2005 - 03:26
exactly... eXeem pretty much sucks... it has spyware in it from what i heard... that right there means alot of people wont use it (including me).

bit torrent is still clearly better if u ask me
#4.2 spUrr on 10 Feb 2005 - 05:08
as of 0.21
spyware has been removed.

Lol, cheer up bram. must be that no one uses his client or donates enough money to him.
Make brams valentine and send him some money
#6 DirtyLarry on 08 Feb 2005 - 21:21
when answering questions, he is straight to the point. you got to give him credit for that.


with that said, i feel as if he was a little to straight to the point. obviously he is a busy man and all of that, but a good amount of the questions were longer than his answers.

and i see me and toastedcrumpets thought the same thing. LOL
#7 imtoomuch on 08 Feb 2005 - 21:31
Talk about fighting for answers. This guy doesn't have much to say at all. I'm guessing he's a shy and quiet guy.
(1 reply) #8 DoNuTs© on 08 Feb 2005 - 21:33
.... Well he's an odd fish. Those were some very short answers.
#8.1 twiglet on 08 Feb 2005 - 22:03
what do you expect, he does "recreational mathematics"
#9 masterren on 08 Feb 2005 - 21:43
Seemed like the questions were more than three times longer than the answers.

isnt he working for valve now? didnt they employ him to work with steam or something?
#10.1 DecoyDuck on 09 Feb 2005 - 00:25
I was wondering this also. I remember when it was big news. Front page, top story: Bram Cohen joins Valve. Page 5, small text, bottom left of page: World Ends next week.

His resume makes no reference to Valve, but it's not up to date as his employment history only goes up to March 2001, unless that is all of his employment - in the general sense - history. That and the Bittorrent site donation page states "I maintain BitTorrent for a living. This is my only job." which leads me to believe that Bram and Valve didn't hit it off.

Oh well.
#10.2 quanta on 09 Feb 2005 - 16:25
Bram mentioned in his blog last month that he hasn't been working at Valve "for a while".

Get your terminology right writers

That line should read "was carrying as much as 30% of the Internets traffic". While Bittorrent can use the web for seeding, the vast majority of data is not transfered over the web.

i read an article a while back . in it he seemed to think he was teh first person to invent breaking up files into a lot of little pieces all over teh net. but far from it. i never really liked bit torrent as it is downloaded a few demo games from sites that had torrent links. download was slow as hell i was luckey to get 4kb at a time if i was luckey yet uploading went as high as 60kb at a time. took forever and a day to download teh 500 meg demos yet when it was all finished i had uploaded 30 times the amount i downloaded. newsgroups even though all files are on the same server have been able to download piece by piece for years before there was a such thing as torrent plus i can download a tv episode at 420 kb at atime sure beats the pos 4 i ever got from torrent
#12.1 illz55 on 08 Feb 2005 - 22:41
Get well seeded and popular torrents and you can get the max speed you can get with your connection easily (at least I do).
#12.2 duphus on 08 Feb 2005 - 22:46
I'm yet to see over 110KBs on my 2mbit line... I would consider the stuff I get popular (80 peers / 20 seeds kind of thing).
#12.3 deiong15 on 08 Feb 2005 - 23:21
i usually get tv shows and used to get them from supernova which had seeds in teh hundreds for teh files and still never ever got a high download at all. i just stick to newsgroups now cause i can download them in minutes instead of days
#12.4 ThaCrip on 09 Feb 2005 - 03:31
i agree... bit torrent is mainly good for older stuff... new stuff u can just get from irc at a much faster speed. or "other" places which i aint gonna talk about
#12.5 AJCrowley Esq on 09 Feb 2005 - 16:06
When certain people used to seed new South Park episodes on the night that they aired, I'd reguarly download them at speeds in excess of 350k/sec. I guess it all depends on the peer cluster, if you're connected to a bunch of people on 300 baud modems on the other side of the world, it's going to be slow, but if you're connected with decent broadband users on the same continent, you can acheive good speeds. Any low speeds are not the fault of the protocol.

I see a lot of people wondering why he is so short with his answers. I wish I could find the link to an article I once read, where another site interviewed him. Bram is actually autistic, and while I can't remember the specifics, I do remember that he's not able to relate to other people very well at all.
#13.1 quanta on 08 Feb 2005 - 23:40
Wired did an interview with him. He has Asperger's syndrome.
#13.2 deadmonkey on 09 Feb 2005 - 21:49
Ahh that explains it. I wish I had known that before complaining about the short answers. I thought he was just being an ass. I used to work with a guy who had Asperger's syndrome and he found it difficult to communicate and understand body language (however I doubt that was a problem in the inteview )

Hi Guys,

Bram just sent me a reply.

Thanks for the link. You should tell the whiners complaining about how short my answers are that I do on average over one interview a day and they should be thankful that I do online interviews at all.


Cut the guy a bit of slack.
#16.1 AminoSC on 09 Feb 2005 - 00:25
I rest my case...he's a pompous a**. He does over one interview a day. What a laugh. This guy was truly my hero till this tiny little nothing of an interview.

#16.2 bogzolla on 09 Feb 2005 - 00:52
i have no problem with his replies
i do have a problem with cheesy and softball questions neowin asked.
#16.3 scaife on 09 Feb 2005 - 05:50
AminoSC (and other people who complain about his answers), are you completely ignorant of the fact that some people have Asperger's syndrome? Be a bit more considerate before badmouthing others. I think he was going pretty easy on you when he called you 'whiners'.
(2 replies) #17 AminoSC on 09 Feb 2005 - 00:22
What a horrible interview. He could have left the questions blank and we'd have just as much information. He totally come across as an a**.
#17.1 AJCrowley Esq on 09 Feb 2005 - 16:08
Not so much so as certain bad mannered posters here however.

By definition, those with AS have a normal IQ and many individuals (although not all), exhibit exceptional skill or talent in a specific area. Because of their high degree of functionality and their naiveté, those with AS are often viewed as eccentric or odd and can easily become victims of teasing and bullying.


Sounds pretty bang on, nice going people.
#17.2 deadmonkey on 09 Feb 2005 - 21:53
Had I/we known he had AS I doubt anyone would have complained.

Reading the interview and not knowing he had AS did make him look like an ass. I am dyslexic and people complain about how I write until they find out I have dyslexia, I don't hold it against them as I can't help it and if they don't know then I am just write badly. People just compare to the norm, I do it so I can't say it is wrong when others do it to me. I doubt very much that Bram takes it personally, if he is hurt by my comments then I apologise.
#18 AminoSC on 09 Feb 2005 - 00:27
The questions were good though
#19 INFERNO2k on 09 Feb 2005 - 00:28
If you read this long interview in Wired magazine last month, he is fairly angered at the whole fiasco that is to come of his program mainly dealing with piracy.

I dont mind short answers, but I do mind when he doesnt answer the questions. Good job Neowin though on getting this.

Yeah, good job, he wasnt really contributing a great deal tho. Strange that he seems very 'middle of the road' about things, not taking any credit for a great protocol, but at the same time not taking any of the blame for the blatant use of it to distribute warez.

What a complete non-entity
#23.1 Jonax on 09 Feb 2005 - 12:47
Is staying away from the spotlight really a bad thing?

In the 80s, Alexei Pajitnov created the code for Tetris and it quickly became popular in Russia's academic circles. The USSR then claimed rights to it and hence a rights war was started between Bullet Proof Software, Mirrorsoft and later Nintendo. The funny thing about this was that despite the argument, Pajitnov was out of the light concerning Tetris and didn't receive anything for it despite the game's popularity.

Fortunately, Pajitnov is nowadays working for Microsoft Game Studios. Point is that just because someone isn't always in the spotlight doesn't make them any less than before
